Airtac GAR Air Regulator GAR30010SJK
The AirTAC Airtac GAR Air Regulator GAR30010SJK is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 MPa range, with 3/8" ports and a built-in circular pressure gauge. It regulates pressure only — it does not filter the air or remove water.

About the Airtac GAR Air Regulator GAR30010SJK
The AirTAC GAR30010SJK is a regulator-only unit that takes a higher supply pressure and holds a steady downstream setting you choose with the knob and read on the fitted circular gauge. It does not filter or clean the air and has no drain bowl or element. This 3/8in model weighs 300 g and regulates the standard 0.05-0.9 MPa (7-130 psi) band.
Its pressed-in self-locking knob keeps the setpoint from drifting when the machine vibrates, so a calibrated pressure stays put through a shift. The balanced adjustment mechanism also holds the setting as the incoming supply varies, which protects downstream components from swings.

Specifications follow the official AirTAC GAR catalogue (pages 228-229). This is a regulator only — it sets and holds a downstream pressure but does not filter the air or separate water. To clean the air as well, use the matching GAFR300 filter-regulator or add a GAF filter upstream. Never run above the 1.5 MPa (215 psi) proof pressure.

A GAR regulates pressure but does not filter — there is no bowl, element or drain code. Need to clean the air too? The matching GAFR300-10 is the same regulator with a built-in filter.
Size Class

All bodies share the same 0.05-0.9 MPa (S) regulated range, 1.0 MPa max and 1.5 MPa proof; the body number sets the port size and the flow the regulator can pass. Bigger ports feed higher air demand. The catalogue plots a flow curve at 0.7 MPa inlet but prints no numeric envelope, so size by port and weight and confirm the curve for a real duty point.

Where the Airtac GAR Air Regulator GAR30010SJK Is Used
CNC fixture clamping
Set a steady 0.4 MPa to a work-holding clamp on a CNC mill, so the part stays put even when the shop air supply dips during another machine's cycle.
Pneumatic bench press
Regulate a bench press to a repeatable 0.6 MPa for consistent forming pressure on small metal parts, without the drift that causes rejects.
Lab air supply
Feed a sensitive lab instrument at 0.2 MPa from a higher plant line, keeping the pressure stable for accurate readings all day.
Is the Airtac GAR Air Regulator GAR30010SJK the Right Regulator?
Choose the GAR300 body for 1/4in to 1/2in port lines; this 3/8in version suits medium-duty tools and single-station fixtures. The standard S type covers 0.05-0.9 MPa (7-130 psi), while the L type only reaches 0.05-0.4 MPa and cannot hit a 0.5-0.6 MPa setpoint. The circular gauge reads MPa/psi on the PT thread, and the J code means no mounting bracket is included, so plan a panel mount or use an existing bracket. A reflux (K) valve is attached, and if the line also needs clean air, use a GAFR300-10 or a GAF filter upstream. The S type's adjustable band is about 2.4x the L type's span (0.85 MPa vs 0.35 MPa).
Quick checklist
- ✓ Body size for your air demand (3/8" here)
- ✓ Type S (0.05-0.9) or L (0.05-0.4 MPa)
- ✓ Gauge fitted, or no gauge (N)
- ✓ Thread PT / G / NPT (sets gauge scale)
- ✓ Bracket kept or removed (J)
- ✓ Need filtration too? Use GAFR300
Installation & Setting Notes
- check Install with the airflow arrow: IN to OUT, knob accessible.
- check Put a filter (GAF or a GAFR) UPSTREAM — a regulator does not clean the air.
- check Set pressure by turning the knob up to the target, then press it in to lock.
- check Keep supply at or below the 1.0 MPa (145 psi) max working pressure.
- check Never exceed the 1.5 MPa (215 psi) proof pressure.
- check Support the 300 g unit on its panel or bracket, not on the tubing.
This is a regulator only — it sets and holds pressure but does not filter or lubricate. Add a GAF filter, a GAL lubricator, or step up to the GAFR300-10 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR30010SJK FAQ
The GAR30010SJK regulates air from 0.05 to 0.9 MPa (7-130 psi) with a max supply of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -20 to 70 C and weighs 300 g with a 3/8in port. The circular gauge reads MPa/psi, and the unit includes a reflux valve but no mounting bracket.
Yes, the J in GAR30010SJK means the mounting bracket is not included, so you need a panel mount or an existing bracket. The K indicates a reverse-flow (reflux) valve is attached to the unit. The GAR itself only regulates pressure; it does not filter the air, so install a GAF or GAFR upstream if you need clean air.
